Specification of Letters Patent.

Patented Nov. 23, 31915.

Application filed March 8, 1913. Serial No. 752,843.

To all whom it may concern:

Be it known that I, JAMns L. GALYEAN, a citizen of the United States, residing at Waterloo, in the. county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Goncrete-M ixers, of which the following is a descr1ption.

My invention belongs to that general class of devices known as concrete mixers or the like, and relates particularly to the type known as non-tilting batch mixers, and suit able discharging mechanism therefor.

The invention has among its objects the production of a device of the kind described that is simple, convenient, durable, compact, efiicient, and satisfactory, and that will not easily get out of repair or adjustment.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

Tn the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a sectional view of the mixing drum, showing my improved dis charge mechanism applied thereto. Fig. 2 is substantially an end elevation of the same. Fig. 3 is a detail view of the inner end of the dischar ing chute in inoperative position. Fig. 1- is substantially a sectional view taken on line 4, 4 of Fig. 1.

Referring to the drawings, 1 is a suitable drum provided with ends 2 and 3, which have openings therethrough for charging at end 2 and discharging the mixture through end 3. As illustrated in the drawings, the complete mixing machine is not shown. Arranged at'the discharging end of the drum is a suitable frame, including the uprights .41 and 5, which are preferably secured or carried bv the machine frame (not shown) carrying the mixing drum and the driving means therefor. Secured to each. of the uprights 4 and 5, are supporting plates 6 and 6, plate 6 being secured to the upright 1, and plate 6 to the upright 5. These plates or supporting members carry or support the lower ends of links, which carry an adjustable chute or scoop 7. The scoop 7 is preferably formed substantiallv in the shape shown in the drawings, so that it may extend through and fit the opening in the dis; charge end 3 of the drum, when inopera links 8 and 11, arranged at each side, the

links 8 being somewhat shorter than the links 11, as shown in Fig. 1. The upper ends of the links 8 and 11 are pivotally secured at 9 and 12 to the scoop, and the lower ends at pointslO and 13 to the plates 6 and 6. The plates and ends of the links being arranged below the points 9 and 12, the weight of the scoop assists in maintaining the same in either position. The scoop is provided with a handle is upon one or both sides for convenience in operating the same.

A frame part or bracket 15 (see Figs. 3 and 4C) is secured to the uprights 4iand 5, and extends under the scoop. Secured to the partslo is what may be termed a slop ring 16, which is formed with flange 17 extending into the-drum. The slop ring prevents the concrete or mixture from slopping out around the chute through the discharge opening. It also serves as a rest for the inner end of the scoop when in inoperative position, as shown by the dotted lines in Fig. 1. The bracket also'serves as a stop when the chute is thrown into operative position, and the scoop, if desired, may be provided with a flange 18 arranged to cooperate therewith. The scoop may be locked in position ,in any satisfactory manner. As shown, it

is lockedin inoperative position, or in mixing position, by a linkor bar 19 secured to the plate 6 at 20, the movement of the same being limited by a slot and pin connection at 26. The opposite end is provided with a notch 30 arranged to cooperate with the pin .29 on the chute 1 1. The weight of the arm or bar 19 tends to maintain it substantially in the position shown in Fig. 1, and when the outer end of the chute is raised, the pin 30 on the chute throws the upper end of the bar toward the drum until the notch comes opposite the pin, at which time the bar falls over into engagement with the pin, locking the chute substantially in theposition shown by the dotted lines in Fig. 1. Means may also be provided for locking the chute in operative position, if desired, a bar or arm .19 being shown in the drawings, provided with notch 30 and cooperating pin 29 on handle or chute.

This bar is similarly connected at points 20 and 26. v

On the interior of the drum are preferably arranged a plurality of buckets 21 and 1 22, and for each bucket 21 is arranged a set or series of blades 23, 24 and 25. These blades are arranged in regular order, or

stepped between the buckets, which are at the discharge side of the drum, and the opposite end or charging end. If desired, there may be a series of blades for each bucket, but, I have shown them only for the alternate buckets v21. 7 I. have not considered it necessary to illustrate the driving mechanism, nor the supporting frame for the drum. It may be mentioned, however, that a gear 28 may be arranged on the exterior "of the drum, and the drum rotated by suitablegearing in mesh therewith. The drum may also be supported upon supporting rolls 27, and maintained in position in any desired Way.

In operation, the drum is rotated in the direction indicated by the arrow in Fig. 2, it being understood that the materials to be mixed are placed in the drumpreferably through the charging opening in the end 2 in any suitable manner. The material is mixed and partially lifted by the blades 23,

'24 and 25, and'carried to the buckets 21,

some, of course, entering the buckets 22, by which it is lifted and dropped and mixed as long as desired. During the mixing operation, the discharge scoop or chute 7 is locked in the position indicated by the dotted lines. When themixture or concrete has been sufficiently mixed, and it is desired to discharge the same, the handles 14: are depressed, throwing the scoop or chute into the position shown in Fig. 1 in the full lines. The

'material dropping from the buckets 21 and "of order. It is easily operated, owing'to thelink connection described,'the weight of the material assisting in operating the chute.

1 Having thus described my invention, it is obvious that various immaterial modificationsmay be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement, or combination of parts herein shown and described, or uses mentioned.

\Vhat I claim as new and desire to secure by Letters Patent is 1. In a device of the kind described and in combination, an adjustable chute, and means for tiltably supporting said chute, including a fixed support and a plurality of links, each having one end pivotally secured to the chute and the other end pivotally secured to the support at a point below the chute.

2. In a device of the kind described and in combination, a tiltable chute, and means for supporting the same, comprising a fixed support and a plurality of links, each having one end pivotally secured to the chute and the other end pivotally secured to the support, and a cooperating lock positioned below the chute and secured to said fixed support.

3. In a device of the kind described and in combination, a tiltable chute, a supporting means therefor including a fixed support and a plurality of links arranged on each side of said chute, and pivotally connected at their opposite ends to the chute and support respectively, a portion of said links of greater length than the others.

4t. In a device of the kind described and in combination, a movable chute and supporting means therefor, including a fixed support, a pair of links secured to said support and to the chute, a second pair of links of slightly greater length than said first pair and pivotally secured to the chute and support, and means carried by said support for maintaining the chute in a tilted position.

5. A device of the kind described comprising the combination of a movable chute, supporting means therefor, including a stationary member carried by said fixed support, and a plurality of pairs of links arranged to pivotally connect the chute to said support, one pair of links of slightly greater length than the other pair, and arranged with the shorter pair between said stationary support and the longer links, and a locking member carried by said fixed support for locking the chute in the desired position.

In teztimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
